The chain will be working with Dreams and Wishes and Forget Me Not Children's Hospice to offer holidays of a lifetime to those in need.
IDILIQ will donate 12 weeks' worth of space to both charities in its collection of Wyndham and Ramada branded resorts in Europe, plus two IDILIQ resorts in Orlando, contributing to a total of 145 weeks donated to UK charities in 2025.
Dreams and Wishes is a multi-award-winning charity helping seriously ill children and their families build memories by granting lifelong wishes.
Forget Me Not Children's Hospice supports and provides outstanding clinical care for families facing or living with the devastating loss of a child.
Kind Holidays offers free holiday accommodation at IDILIQ's collection of resorts that combine the convenience of a self-catering apartment, townhouse or lodge with the luxuries and facilities for the entire family.
Other charity partners supported by IDILIQ include Give Us Time, Noah's Ark Children's Hospice and Carers Trust.
Grant Peires, Director of Communications at IDILIQ, said: "We have a unique opportunity to help bring joy, treasured memories and respite to families going through unimaginable physical and/or emotional trauma. I urge all hoteliers to consider joining this incredibly impactful and meaningful initiative.
"From hotel porter to our founder, nothing like this has filled our team members with such pride and purpose. Being able to give back in such a personal way, has had the most profound effect on them and naturally improves staff performance, retention, and recruitment.
"The level of gratitude that is shown by these most special of families touches the core of our humanity."
